Brake Fluid Reservoir Port Structure to Prevent Reverse Flow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electric vehicles with electronic brake systems, the conventional remote-type reservoir design leads to a reverse flow of brake fluid due to fluid biasing during deceleration, acceleration, or turning, which deteriorates brake performance by reducing fluid levels in the main reservoir tank.
Innovation Solution
A reservoir system comprising a first reservoir tank, a second reservoir tank with a port portion and a connection hose, where the port portion is designed with ribs and a fluid reserving portion to ensure the port is submerged in brake fluid, preventing backflow by surrounding the port with ribs and allowing fluid to flow through a passage, thus maintaining fluid levels during vehicle maneuvers.

Engineering Contradiction Analysis
1Volume of moving object
If the vertical distance L1 between the main reservoir tank and the remote reservoir tank is reduced and the horizontal distance L2 is increased, then the space utilization is improved, but the reverse flow of brake fluid increases
Solution Approach 1:
A one-way valve is introduced as an intermediary component in the connection hose between the remote reservoir tank and main reservoir tank. This valve allows brake fluid to flow only in the forward direction (from remote to main tank) and blocks reverse flow, thereby maintaining brake fluid level stability while permitting flexible spatial arrangement of the reservoir tanks.
Solution Approach 2:
The invention changes the flow direction parameter of the brake fluid by implementing asymmetric flow characteristics through the one-way valve. The valve structure allows fluid passage in one direction while blocking it in the opposite direction, thus preventing reverse flow caused by vehicle deceleration, acceleration, or turning maneuvers.
2Volume of moving object
If the conventional remote-type reservoir design is used, then the space constraint in the engine room is addressed, but the brake performance deteriorates due to reverse flow
Solution Approach 1:
The one-way valve serves as a mediator that protects the brake system performance by preventing reverse flow of brake fluid. This allows the remote reservoir tank design to be maintained for space efficiency while ensuring brake performance is not compromised by fluid backflow during vehicle maneuvers.
Solution Approach 2:
The one-way valve provides preliminary anti-action by preemptively blocking the potential reverse flow of brake fluid before it can occur. The valve is positioned in the connection hose to prevent brake fluid from flowing back into the remote reservoir tank during deceleration, acceleration, or turning, thus maintaining consistent brake fluid levels and performance.

Disclosed are a reservoir for a brake apparatus of a vehicle. The reservoir includes a first reservoir tank, a second reservoir tank formed to be spaced apart from the first reservoir tank and provided with a port portion for supplying a brake fluid to the first reservoir tank, and a connection hose configured to connect the port portion to the first reservoir tank so that the brake fluid of the second reservoir tank is transferred to the first reservoir tank, wherein the port portion includes a first port unit protruding to the inside of the second reservoir tank and a second port unit protruding to the outside of the second reservoir tank.
